Boston Micro Fabrication is on a mission to enable miniaturization using micro-precision 3D printing. We set out on this mission when we globally launched in early 2020 — with the intention to serve a previously underserved market — additive manufacturing of micro parts. Electronics, packaging, components, medical devices — these are all getting smaller and smaller. The major barrier that is holding back miniaturization in product design, is the ability to quickly and cost effectively make very small parts. This is where we come in.

Meet our CEO, John Kawola and learn more about us, our mission and the problems we are trying to solve for micro part manufacturers globally.

Micro 3D Printing: Enabling Miniaturization

Additive Manufacturing has been around for 30 years – used in prototyping and now moving into production, but the biggest value of AM comes from prototyping and production of parts that are difficult to manufacture using other more traditional methods.

It is a common understanding that nothing is more difficult to produce – for prototypes or production parts – than when miniaturization is critical.

As products get smaller and smaller, the impact on product development is significant, as the challenge to efficiently and cost effectively manufacture small components increases. Current manufacturing methods such as micromachining, micro molding and lithography add multiple steps, long wait times and are very expensive. Learn how micro 3D printing is enabling miniaturization and why manufacturability is no longer the limiting factor in product design.

Learn How PµSL Works

BMF’s printers use a patented 3D printing technology called Projection Micro Stereolithography (PµSL) to print ultra-high resolution, precision, and accuracy parts. Wondering how it works? Watch this video animation explaining BMF’s PµSL process.

PµSL prints in the top down direction of SLA. However rather than using a small spot laser, the entire image, or a section of the image is cured as done in DLP processes. A thin plastic membrane that is consistently stretching and leveling the uncured resin within the vat. This process fabricates micro-sized parts with top notch resolution, at much faster speeds than traditional microfabrication techniques. By using this technology, current additive users can push and extend the limitations of traditional SLA and DLP technologies while new users can unlock capabilities within their business that were once unachievable.
